CARLSON BUCK BAKE OR HAY SWEEP Filed Sept. 18, 1928 dition to this standard, side standards 29 are provided which are of less height than the standard 26 and are secured at their lowei` ends to the beam. Diagonal braces 30 ex- Ythe tractor by extending the beams l0 beneath 4 lthe front axle of the tractor until their rear ends can be secured to .the draw bar-D thereof.

tend from the upper ends of the standards y29 tothe beam and are secured thereto and lIlhese beams are then elevated at their forward ends Vand secured to the front axle A of the `tractor by U-bolts 34 or other convenient means. Due to its rugged construction, this may be conveniently accomplished by allowing the device Vto lay upon the ground and Vrunningthe front Ywheels ofthe tractor over the same until the beams are properly located.

. In combination with this structure, I proy' vide a means for oscillating the rake upon the v,mounting provided by the bearings 15,'which include a vertical post 35. This post may beseCured at any suitable point but is preft brace 37 maybe extended from the post 35.

, erablysecured at its lower end to one of the f side beams B of the tractor frame and is braced thereto, as indicated at 35 to the other ofthe tractor frame beams. An additional Upon .the upper end of the post, I mount spaced collars 38, which are rotatably engaged by bearings 879 and 4() surrounding the post and rotatable thereon. These bearings are formed one upon the inner end of a lever ,4l andthe other uponthe inner end of a .brace 42 for the lever. This lever has secured ,n thereto, by a connection 43 longitudinally of 45.

Vthe lever, a rod 44 having at its forward end a hook 45 adapted to interchangeably engage in the links of the chain 28. To the outer ends vof the lever is connected one end Tito of alinkf46, the opposite end of which is connected vto a ratchet adjusting hand lever Vof any ordinary or usual construction. This hand lever may be conveniently located with respect to the operator of the tractor and is preferably carried directly by the tractor.

It will be obvious that in operation of the device, the lever 47, while providing means determining the-limit of approach of the exhas such yconnections with these rake lteeth that the. rake teeth may elevate, slackening the chains 28. This results in a loose mounti ing for the teeth, preventing breakage thereof due to collection of hay beneath the teeth i for casual engagement 'thereof with the vvground.' In operation, `'thedevice is driven and secured to along the windrow until the desired amount of hay is collected when it may be transported to the stack or other point, where it is desired. Reaching the desired point, the hay may be released yby lowering the teeth until the hay supported thereby comes into engagement with the ground when the movement of the tractor may be reversed.

Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from theV spirit of the invention, I do not limit myself to such specific structure except` as hereinafter claimed.

. Y I claim k. 1. buck rake attachment forA tractors comprising a horizontally disposed frame adapted to be secured to the tractor frame, a

forwardly. projecting `rake Asecured to the horizontal frame, an upstanding backl secured to the rake and positioned forwardly of the rear endthereof, an angularly inclined brace secured to the rake and engaging the back, and` operating means secured tothe tractor and engaging the back structure whereby to swing the rake into orfout of engagement with the ground, said, operating means comprising a vertically/disposed support, means for mounting thersupport on a tractor frame rearwardly of the rake structure, a swing-A able arinmounted `onthe support and ex-v I tending o'hutwrardly therefrom in a substantially horizontal plane, means connecting the arm to the upper portion ofthe'back of the rake, a pivoted operating lever and means connecting the operating lever to the arm whereby to swing the arm coactively with the rocking of the lever, said rake comprising a. plurality of spaced parallel tines, a transverse bar secured to the rearvend of said tines, a secondv transverse member secured to said tines forwardly-of the rear end thereof, angularly positioned braces secured to each of lsaid transverse members whereby to holdsaid tines against llateral movement, and'x a pair of outwardly diverging bracesY secured lto said frame .andV pivotally engaging said first transverse member.
